CVE-2026-42846: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in MacWarrior clipbucket-v5
ClipBucket v5 is an open source video sharing platform. Prior to version 5.5.3 - #140, ClipBucket's Remote Play feature allows any authenticated user to add a video by importing an external URL as the source. Some shell commands are run with the URL as a parameter. The URL is concatenated directly into shell commands without escaping then executed, so any shell metacharacter in the URL is interpreted. This results in arbitrary command execution. This issue has been patched in version 5.5.3 - #140.
AI Analysis
Technical Summary
ClipBucket v5's Remote Play feature allows authenticated users to import videos via external URLs. Before version 5.5.3, these URLs are directly concatenated into shell commands without escaping special characters, leading to OS command injection (CWE-78). This enables an attacker to execute arbitrary commands on the underlying operating system. The issue is fixed in version 5.5.3.
Potential Impact
Successful exploitation allows an attacker with authenticated access to execute arbitrary OS commands on the server hosting ClipBucket, leading to full compromise of confidentiality, integrity, and availability of the system. The CVSS 3.1 base score is 9.8 (critical), reflecting network attack vector, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade ClipBucket v5 to version 5.5.3 or later, where the vulnerability is patched. No other official remediation or temporary fixes are documented. Until upgraded, restrict authenticated user access to trusted users only.
